Therefore, the above mentioned terms cannot be understood as a limitation to the present application.

The technical solutions of the present application will be illustrated in more details below combining with the accompanying FIGS. 1 to 9.

Referring to FIG. 1, an embodiment of the present application provides an L-shaped shear wall module including an L-shaped outer pattern plate 100, an L-shaped inner pattern plate 200, and connectors 300 connected between the L-shaped outer pattern plate 100 and the L-shaped inner pattern plate 200. Optionally, materials of the L-shaped outer pattern plate 100, the L-shaped inner pattern plate 200, and the connectors 300 are expanded polystyrene. Optionally, the L-shaped outer pattern plate 100, the L-shaped inner pattern plate 200, the connectors 300, a first pattern plate 110, a second pattern plate 120 and the connectors 130 are formed to be a whole by a mold box. The L-shaped outer pattern plate 100 and the L-shaped inner pattern plate 200 are arranged in parallel to each other. The L-shaped inner pattern plate 200 includes a first inner pattern plate 220 and a second inner pattern plate 230 which are perpendicular to each other. A corner transition block 210 is disposed at a corner of the L-shaped inner pattern plate 200. The corner transition block 210 has a protruding surface protruding toward the L-shaped outer pattern plate 100; an end of the protruding surface extends to an outer side surface of the first inner pattern plate 220; and another end of the protruding surface extends to an outer side surface of the second inner pattern plate 230.

The protruding surface of the corner transition block 210 and the inner surface of the L-shaped outer pattern plate 100 jointly enclose a concreting cavity 400 at the corner for concreting reinforced concrete, which effectively increases the cross-sectional area of the concreting cavity at the corner of the L-shaped shear wall module, improves the strength and load-bearing capacity of the corner of the L-shaped shear wall module, and enhances the firmness of the wall. In addition, when concrete in the concreting cavity has solidified, the corner transition block 210 can be cut off. After the corner transition block 210 is cut off, the corner of the L-shaped inner pattern plate is right-angled in shape, thereby guaranteeing the strength of the corner, and reducing occupied indoor space as well.

Optionally, the protruding surface is an arc-shaped curved surface protruding towards the L-shaped outer pattern plate. One end of the arc-shaped curved surface extends to the outer side surface of the first inner pattern plate 220, and the other end of the arc-shaped curved surface extends to the outer side surface of the second inner pattern plate 230. The arc-shaped curved surface and the L-shaped outer pattern plate 100 jointly enclose the concreting cavity 400. The concreting cavity 400 has a relatively large cross-sectional area and a relatively good performance of bearing forces. After the concrete is poured into the concreting cavity 400, the corner transition block 210 can be cut off, and used for constructing a buttress column directly, without providing a special buttress column pattern plate. Compared with the existing buttress column, occupies less indoor space.

Optionally, as shown in FIG. 1, the cross section of the corner transition block 210 can be triangular, arc-shaped, semi-circular in shape, or the like. In an embodiment, the corner transition block 210 is in a shape of a right triangular prism, and the right triangular prism includes a first side surface 211 and a second side surface 212 which are perpendicular to each other. The first side surface 211 is rigidly connected to the first inner pattern plate 220, and the second side surface 212 is rigidly connected to the second inner pattern plate 230. The first side surface 211 and a surface away from the L-shaped outer pattern plate 100, of the first inner pattern plate 220 are coplanar; that is, in a direction perpendicular to the first inner pattern plate 220, the L-shaped inner pattern plate 200 retracts inwards at the corner, and the retracted depth is equal to a thickness of the first inner pattern plate 220. The second side surface 212 and a surface away from the L-shaped outer pattern plate 100, of the second inner pattern plate 230 are coplanar; that is, in a direction perpendicular to the second inner pattern plate 230, the L-shaped inner pattern plate 200 retracts inwards at the corner, and the retracted depth is equal to a thickness of the second inner pattern plate 220. The first side surface 211, the second side surface 212, one end surface of the first inner pattern plate 220, one end surface of the second inner pattern plate 230, and the L-shaped outer pattern plate 100 jointly enclose the concreting cavity 400. The concreting cavity 400 has a relatively large cross-sectional area and relatively good performance of bearing forces. After concrete is poured into the concreting cavity 400, the corner transition block 210 can be cut off, and used for constructing a buttress column directly, without providing a special buttress column pattern plate. Compared with the existing buttress column, occupies less indoor space. The cross-sectional area of the concreting cavity 400 at the corner of the L-shaped shear wall module is effectively increased, thereby improving the strength and the load-bearing capacity of the corner of the L-shaped shear wall module, and enhancing the firmness of the wall. In addition, when the concrete in the concreting cavity has solidified, the corner transition block 210 can be cut off. After the corner transition block 210 is cut off, the corner of the L-shaped inner pattern plate is right-angled in shape, thereby guaranteeing the strength of the corner, and reducing the occupied indoor space as well.

Optionally, a side edge at an intersection between the first side surface 211 and the second side surface 212 is a rounded edge, thereby effectively reducing the stress concentration at the corner of the L-shaped shear wall module, improving the strength and load-bearing capacity of the corners of the L-shaped shear wall module, and enhancing the firmness of the wall.

Optionally, as shown in FIGS. 1 and 2, a protruding block 213 is provided on the top surface of the triangular prism, and the protruding block 213 can be triangular, trapezoidal, circular, oval in shape, or the like. In an embodiment, the protruding block 213 is triangular in shape, and a groove 214 matching the protruding block 213 is disposed on the bottom of the triangular prism. When two adjacent upper and lower L-shaped shear wall modules 10 are vertically spliced, the protruding block 213 and the groove 214 fit together to achieve accurate positioning and installation.

Referring to FIGS. 1 to 3, in an embodiment, a first projecting part 110 is provided on the top of the L-shaped outer pattern plate 100; a plurality of first inner protrusions 130 are arranged at intervals at the inner side of the first projecting part 110; and a plurality of first outer protrusions 150 are arranged at intervals at the outer side of the first projecting part 110. As shown in FIG. 1, a height of the first projecting part 110 is greater than a height of each of the first inner protrusions 130, and the height of the first projecting part 110 is greater than a height of each of the first outer protrusions 150. As shown in FIG. 2, the bottom of the L-shaped outer pattern plate 100 is provided with a first groove 120 matching the first projecting part 110; the bottom of the L-shaped outer pattern plate 100 is provided with first inner grooves 140 matching the first inner protrusions 130; and the bottom of the L-shaped outer pattern plate 100 is provided with first outer grooves 160 matching the first outer protrusions 150. As shown in FIG. 1, the top of the L-shaped inner pattern plate 200 is provided with a second projecting part 240; a plurality of second inner protrusions 241 are arranged at intervals at the inner side of the second projecting part 240; a plurality of second outer protrusions 243 are arranged at intervals at the outer side of the second projecting part 240; a height of the second projecting part 240 is greater than a height of each of the second inner protrusions 241; and the height of the second projecting part 240 is greater than a height of each of the second outer protrusions 243. As shown in FIG. 2, the bottom of the L-shaped inner pattern plate 200 is provided with a second groove 250 matching the second projecting part 240; the bottom of the L-shaped inner pattern plate 200 is provided with second inner grooves 242 matching the second inner protrusions 241; and the bottom of the L-shaped inner pattern plate 200 are provided with second outer grooves 244 matching the second outer protrusions 243. When one L-shaped shear wall module 10 is vertically spliced together with another L-shaped shear wall module 10, the first projecting part 110, the first inner protrusions 130, the first outer protrusions 150 provided on the top of the L-shaped outer pattern plate 100 of the first L-shaped shear wall module 10 fit and are installed correspondingly in the first groove 120, the first inner grooves 140, and the first outer grooves 160 provided on the bottom of the L-shaped outer pattern plate 100 of the second L-shaped shear wall module 10, respectively. Meanwhile, the second projecting parts 240, the second inner protrusions 241 and the second outer protrusions 243 provided on the top of the L-shaped inner pattern plate 200 of the first L-shaped shear wall module 10 fit and are installed, respectively. Moreover, the height of the first projecting part 110 is greater than the height of each of the first inner protrusions 130; the height of the first projecting part 110 is greater than the height of each of the first outer protrusions 150; the height of the second projecting part 240 is greater than the height of each of the second inner protrusions 241; and the height of the second projecting part 240 is greater than the height of each of the second outer protrusions 243. Accordingly, the internal concrete is effectively prevented from pouring out through a gap between the two spliced L-shaped shear wall modules, thus avoiding a water loss of the concrete, ensuring a normal proportion of water in the concrete, and further ensuring the strength of the wall after the concrete has solidified. Besides, since the water loss of the concrete is avoided, the water in the concrete plays a role in curing the concrete, thus enabling the newly poured concrete to solidify at a normal rate or at an increased rate, and enhancing the strength of the wall. In addition, the water in the concrete is prevented from flowing out through the gap between the two spliced shear wall modules 100, thus guaranteeing the cleanliness of the wall and making the wall more beautiful, effectively avoiding a fracture of the connector 300 and preventing a swelled portion from occurring between the two spliced upper and lower L-shaped shear wall modules 10, improving the construction progress, and enhancing the firmness of the wall.

Optionally, the first inner protrusions 130 and the first outer protrusions 150 are arranged to be directly opposite one to one or staggered at two sides of the first projecting part 110, and the second inner protrusions 241 and the second outer protrusions 243 are arranged to be directly opposite one to one or staggered at two sides of the second projecting part 240, so that integration of insertion and positioning is achieved, and that special positioning steps are omitted, and that the insertion of the two adjacent upper and lower L-shaped shear wall modules 10 is more firm, avoiding a separation between modules when concrete is being poured.

Optionally, as shown in FIG. 1, the first inner protrusions 130 and the first outer protrusions 150 are arranged to be directly opposite one to one, and have the same height; and the second inner protrusions 241 and the second the second outer protrusions 243 are arranged to be directly opposite one to one, and have the same height. Such an arrangement is convenient for mold stripping and molding. A difference between the height of the first projecting part 110 and the height of the first inner protrusion 130 ranges from 3 mm to 6 mm, and a difference between the height of the second projecting part 240 and the height of the second inner protrusion 241 ranges from 3 mm to 6 mm. Optionally, an interval between two adjacent first inner protrusions 130 ranges from 55 mm to 65 mm, and an interval between two adjacent second inner protrusions 241 ranges from 55 mm to 65 mm. The first inner protrusions 130 and the two adjacent second inner protrusions 241 are densely arranged. When one L-shaped shear wall module 10 and another L-shaped shear wall module 10 are spliced vertically, the contact area of insertion is large, thus effectively preventing the internal concrete from flowing out through the gap between two upper and lower L-shaped shear wall modules 10, avoiding the fracture of the connector 300 and prevent a swelled portion from occurring between the spliced two upper and lower L-shaped shear wall modules 10, improving the construction progress, and enhancing the firmness of the wall.

Optionally, referring to FIGS. 1 and 3, the cross sections of the first inner protrusion 130, the first outer protrusion 150, the second inner protrusion 241, and the second outer protrusion 243 are all trapezoidal in shape. In a vertical direction, the edges of the first inner protrusion 130, the first outer protrusion 150, the second inner protrusion 241, and the second outer protrusion 243 are all rounded edges. The two adjacent upper and lower L-shaped shear wall modules 10 have relatively high connection strength and rigidity after they are inserted one to another, which can effectively prevent the upper and lower modules from being separated from each other when the concrete is being poured, and can further prevent the concrete from flowing out through the gap and causing the fracture of the connectors 300 due to excessive forces exerted on two sides of the connectors 300. The L-shaped shear wall module 10 is prevented from being damaged due to the collisions of sharp corners during transportation.

Optionally, referring to FIGS. 1 and 3, H1 denotes a distance between the inner side surface of the first projecting part 110 and the inner surface of the L-shaped outer pattern plate 100, and H2 denotes a distance between the outer side surface of the first projecting part 110 and the outer surface of the L-shaped outer pattern plate 100, where H1<H2. H3 denotes a distance between the inner side surface of the second projecting part 240 and the inner side surface of the L-shaped inner pattern plate 200, and H4 denotes a distance between the outer side surface of the second projecting part 240 and the outer side surface of the L-shaped inner pattern plate 200, where H3<H4. H1 is in a range from 13 mm to 17 mm; H2 is in a range from 23 mm to 27 mm; t H3 is in a range from 13 mm to 17 mm; and H4 is in a range from 23 mm to 27 mm. H1<H2, and H3<H4, which can reduce the impact of the concrete on the module when the concrete is being poured, and effectively prevent the fracture of the connectors 300.

Optionally, referring to FIGS. 1 to 6, a third projecting part 170 protruding outward is provided on an end surface of the L-shaped outer pattern plate 100, and a cross section of the third projecting part 170 is trumpet-shaped. A third groove 180 matching the third projecting part 170 is disposed on another end surface of the L-shaped outer pattern plate 100. An end surface of the L-shaped inner pattern plate 200 is provided with a fourth projecting part 260 protruding outward. A cross section of the fourth projecting part 260 is trumpet-shaped. A fourth groove 270 matching the fourth projecting part 260 is disposed on another end surface of the L-shaped inner pattern plate 200, and the third projecting part 170 and the fourth projecting part 260 are arranged in opposite directions. When the L-shaped shear wall module 10 is spliced horizontally with other straight shear wall modules, the insertion is more reliable and not easy to disconnect. The present module can also be combined with a concrete shear wall to serve as a special-shaped buttress for reinforcement at the corner of the shear wall or at an intersection of the wall. Compared with the existing rectangular buttress products in a market, the present module takes up less indoor space. The module of the present application can be effectively combined with the straight pattern plate and is easy to schedule, and there is no need to produce a rectangular frame column pattern plate.

Optionally, as shown in FIGS. 1 and 3, an identification portion is disposed on the outer surface and proximate to the middle portion of the L-shaped outer pattern plate 100, and a dove-tail groove on the middle position of the outer surface of the L-shaped outer pattern plate 100 is filled to form the identification, in order to mark a product number, a company name, a telephone number, etc. A plurality of first dove-tail grooves 190 are arranged at intervals on the inner surface and the outer surface of the L-shaped outer pattern plate 100, and opening edges and inner edges of the first dove-tail grooves 190 are all rounded edges. A plurality of second dove-tail grooves 280 are arranged at intervals on the inner side surface and outer side surface of the L-shaped inner pattern plate 200, and opening edges and inner edges of the second dove-tail grooves 280 are all rounded edges. Both the first dove-tail groove 190 and the second dove-tail groove 280 are sloped, that is, the upper parts thereof are narrow, and the lower parts thereof are wide, so as to facilitate demolding in a workshop. The opening edges and the inner edges of the first dove-tail grooves 190 are all rounded edges. Optionally, an interval between two adjacent first dove-tail grooves 190 is 30 mm. An interval between two adjacent second dove-tail grooves 280 is 30 mm. Due to the arrangement of the first dove-tail grooves 190 and the second dove-tail grooves 280, the external coated anti-cracking mortar has a reliable mechanical engagement with the surfaces, thereby effectively preventing the externally coated anti-cracking mortar from falling. The internal poured concrete has a reliable mechanical engagement with the surfaces, and the concrete and EPS can function together, thus improving the bonding force of the anti-cracking mortar or the bonding force of the concrete combining with the EPS, preventing the module from being damaged due to the collisions of the sharp corners during transportation, and moreover, facilitating demolding and improving bonding forces.

Optionally, an inserting board is arranged in oppositely disposed first dove-tail groove 190 and second dove-tail groove 280 among the first dove-tail grooves 190 on the inner surface of the L-shaped outer pattern plate 100 and the second dove-tail grooves 280 on the outer side surface of the L-shaped inner pattern plate 200, and the inserting board divides the concreting cavity 400 enclosed by the L-shaped outer pattern plate 100 and the L-shaped inner pattern plate 200 into a concrete concreting cavity 400 and a silt concreting cavity 400. Concrete and silt are poured separately, which is more economical. A special-shaped column of any size can be formed. As shown in FIG. 1, reinforced concrete can be poured inside the special-shaped column, and thermal insulation mortar or common mortar can be poured outside the areas divided by the inserting board, which can effectively reduce the cost of construction (the cost of construction of the mortar per cubic meter is about 40% of that of the concrete), guarantee safety, and ensure beams and columns not to be exposed.

Optionally, as shown in FIGS. 1 to 3, the connectors 300 each includes a first connector 310 and a second connector 320. A length of the first connector 310 in the vertical direction is greater than a length of the second connector 320 in the vertical direction, and upper surfaces of the first connector 310 and the second connector 320 are located in the same horizontal plane, or lower surfaces of the first connector 310 and the second connector 320 are located in the same horizontal plane. Optionally, the length of the first connector 310 in the vertical direction is twice the length of the second connector 320 in the vertical direction. Along the length direction of the L-shaped shear wall module 10, the first connector 310 and the second connector 320 are arranged to be staggered, which can guarantee the strength while effectively avoid the waste of materials to meet the requirements of uniformity and economy of the module. The sharp corners of the first connector 310 and the second connector 320 are chamfered to facilitate demolding. The staggered arrangement of the first connector 310 and the second connector 320 makes a center penetration portion of the module to be effectively strengthened. Compared with a serpentine penetration portion of the existing module in a market, a pull-beam-typed direct penetration portion bears forces directly. Moreover, the arrangement manner of the first connector 310 and the second connector 320 can increase the transportation efficiency by about 15%-20%.

Optionally, the upper surfaces of the first connector 310 and the second connector 320 are located in the same horizontal plane. The upper surfaces of the first connector 310 and the second connector 320 are both provided with a plurality of receiving grooves 330, and a reinforcing bar is arranged in each of the receiving grooves 330. Optionally, convex ribs 340 protruding upwards are arranged at intervals on the upper surfaces of the first connector 310 and the second connector 320, and the receiving groove 330 for receiving the reinforcing bar is formed between two adjacent convex ribs 340. Optionally, three receiving grooves 330 are provided on each of the surfaces of the first connector 310 and the second connector 320, and on the basis of requirements, one reinforcing bar can be arranged in a middle receiving groove, two reinforcing bars are arranged in the receiving groove at one side, and three bars arranged in the receiving groove at another side. In such an arrangement, not only can the strength of the shear wall be increased, but more importantly, reinforcing bars of different numbers can be arranged in each position according to requirements, to adjust the rigidity of the shear wall as required by construction. The convex ribs 340 will not weaken the cross sections of the first connector 310 and the second connector 320, nor will they cause defects on the upper surfaces of the first connector 310 and the second connector 320, thereby further preventing the connectors 300 from breaking, and making it convenient for an operator to assemble reinforcing bars without stretching out his/her hands too deep into the module. The arrangement of the connectors 300 makes vertical gaps in the concrete shear wall. After concrete is poured, only EPS but no concrete exists at locations where the connectors 30 are disposed. As the elastic modulus of the EPS is much greater than that of the concrete, and is equivalent to that of the concrete shear wall formed with gaps, the shear wall with vertical gaps has good integrity in an elastic range, has rigidity reduced little, and has better anti-shearing and bearing capacity than a conventional shear wall does.

As shown in FIGS. 4 to 6, another embodiment of the present application provides an L-shaped shear wall module 10, which has basically the same structure as the L-shaped shear wall module 10 provided in the above-described embodiment, and is applicable to corners of different walls. As shown in FIG. 1 and FIG. 4, the differences therebetween are that the end surfaces, where the third projecting part 170 and the fourth projecting part 260 of the L-shaped shear wall module 10 of this embodiment are disposed respectively, are contrary to the corresponding end surfaces where the third projecting part 170 and the fourth projecting part 260 of the above-described embodiment are disposed respectively; and that, as shown in FIGS. 2 to 5, the end surfaces, where the third groove 180 and the fourth groove 270 of this embodiment are disposed respectively, are contrary to the corresponding end surfaces where the third groove 180 and the fourth groove 270 of the above-described embodiment are disposed respectively.

An embodiment of the present application provides a shear wall, which includes a plurality of L-shaped shear wall modules 10 in any one of the above technical solutions. The plurality of L-shaped shear wall modules 10 are vertically spliced to form a whole shear wall. In an actual construction process, a plurality of L-shaped shear wall modules 100 are assembled (via insertion up and down) to form a wall without a need to disassemble the modules, and concrete is poured into the wall to form a wall with certain strength, rigidity, and thermal insulation performance.

Referring to FIGS. 7 to 9, an embodiment of the present application provides a construction method of a building shear wall, using the L-shaped shear wall module 10 as described in any one of the above technical solutions. Optionally, the materials of the L-shaped outer pattern plate 100, the L-shaped inner pattern plates 200 and the connectors 300 are expanded polystyrene. The method using the L-shaped shear wall module 10 includes the following steps.

A plurality of L-shaped shear wall modules 10 are spliced vertically to form the concreting cavity.

Filler is poured into the concreting cavity. As shown in FIG. 7, the filler can be concrete, mortar, etc.

After the filler solidifies, the corner transition block 210 at the corner of the L-shaped inner pattern plate 200 is removed to expose a surface layer of the filler in a right-angled or curved shape. Moreover, as shown in FIG. 8, two ends of the surface layer of the filler extend to the first inner pattern plate 220 and the second inner pattern plate 230 respectively.

A coating layer is coated on the surface layer of the filler and the outer surfaces of the remaining portion of the L-shaped inner pattern plates 200. As shown in FIG. 9, the coating layer can be an anti-cracking mortar layer coated on the surface layer of the filler and the outer surfaces of the first inner pattern plate 220 and the second inner pattern plate 230. In the construction method of the building shear wall, when the filler such as concrete in the concreting cavity has solidified, the corner transition block 210 can be cut off, and the corner of the L-shaped inner pattern plate without the corner transition block is right-angled in shape to guarantee the strength of the corner and reduce the occupied indoor space as well.

The above L-shaped shear wall module includes the L-shaped outer pattern plate, the L-shaped inner pattern plate, and the connectors connected between the L-shaped outer pattern plate and the L-shaped inner pattern plate. The L-shaped outer pattern plate and the L-shaped inner pattern plate are arranged in parallel to each other, and the L-shaped inner pattern plate includes a first inner pattern plate and a second inner pattern plate perpendicular to each other. The corner transition block is disposed at the corner of the L-shaped inner pattern plate; the corner transition block has a protruding surface that protrudes toward the L-shaped outer pattern plate; and one end of the protruding surface extends to the outer side surface of the first inner pattern plate, and the other end of the protruding surface extends to the outer side surface of the second inner pattern plate. The protruding surface of the corner transition block and the inner surface of the L-shaped outer pattern plate jointly enclose the concreting cavity at the corner for concreting reinforced concrete, which effectively increases the cross-sectional area of the concreting cavity at the corner of the L-shaped shear wall module, improves the strength and the load-bearing capacity of the corner of the L-shaped shear wall module, and enhances the firmness of the wall. In addition, when the concrete in the concreting cavity has solidified, the corner transition block can be cut off. After the corner transition block is cut off, the corner of the L-shaped inner pattern plate is right-angled in shape, thereby guaranteeing the strength at the corner and reducing the occupied indoor space as well.

The technical features of the above-described embodiments may be arbitrarily combined. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction between the combinations of these technical features, all should be considered within the scope of the disclosure.

What described above are several embodiments of the present application, and these embodiments are specific and in details, but not intended to limit the scope of the present application. It should be understood by the skilled in the art that various modifications and improvements can be made without departing from the scope of the present application.
